Hey JupiterSky, does sound like a unique/unusual thing since there shouldn't be any showstoppers on the part of Proton or the game itself, and plenty of others are using it normally, so it likely has something to do with your setup. Unfortunately I can't troubleshoot it myself since I'm not familiar with that sort of thing, though perhaps with more info others could offer advice? Like anything else that might be unique about your system. There are also likely going to be more people on the Discord than checking here, but I'll point out this thread and see if anyone has any input.
